15APER-MAKING MACHINE.

Application filed March 2, 1922. Serial No. 540,407.

To all whom it may concern.

Be it known that 1, CHARLES C. CLUTCH, a citizen of the United States, residing at Yorklyn, in the county of New Castle and State of Delaware, have invented new and useful Improvements in a Paper-Making Machine, of which the following is a specification.

My invention relates to new anduseful improvements in a paper making machine and more particularly with relation to the apron board thereof, the object of which is to provide a simple and effective means for regulating the flow of paper stock according to the different natures and weights thereof.

Another object of the invention is to pro- 7 vide for adjusting the apron board vertically and also horizontally relative to a slice bar so thatthe apron may be movedinto close proximity to said'slice bariwhen running free stock and may be moved therefrom when running slow stock.- 1

Another object of the invention is to provide an adjustable apron board whereby it may be quickly and conveniently adjusted transversely of the machine to control the size of thepaper sheet without the necessity of'detaching any portion of the apron board. A further object of the invention is to so construct and arrange the apron parts or sections that they will not curl along their edges or at their corners when being adjusted.

With these ends in view, this invention consists in the details of construction nd combination of elements hereinafter set forth and then specifically designated by the claims. v

In order thatthose skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application,

in which .Flg. 1, is a fragmentary perspective View of a paper making machlne 1n the-region of p the apron board.

In carrying out nay-invention as here embodied, 2 represents a paper making machine provided with the Fourdrinier. wire 3 running over rollers, one of which is shown at 4,

To suitable parts of the frame of the machine at each side of the F ourdrinier wire is secured a lOIaCkeh50OI1S1StlIlg of an upright 6 having a verticallongitudinal slot 7 therein for the passage of a suitable at-:

taching means -'8, such as a bolt;which is screwed "into the machine frame and, by which the bracket is held in any desired'ven tical adjustment, as will be obvious. jecting from the upper end'of the upright 6 is an arm 9 having a longitudinal slot 10 therein for the passage of suitable fastening means 11, such as a bolt or screw which has.

threaded connection with theapro-n support 12, said fastening means 11 preventing the Pro-' accidental displacement of thesupport 12 1 pcrinittinga longitudinal movement of the latter relative to the armi9 ofthe bracket. The arm 9 is also provided ;with a pairof spaced lugs 13 and 14' one on each side of the slot 10 and threaded through theselugs are the adjusting screws- 15 and 16 which engage the back and front respectively of the support 12 so that as one isbackedout and the other screwed inwardly the support 12 will be moved in the desired direction.

The support 12 is provided with a longitudinal groove 17 preferably arcuate in cross section and in which aremounted the bars 18, eachof which has secured thereto the inner or rear member 19 of; the shields 20, the outer or forward members 21 projectingforwardly beyond th'efront edge of the support 12 at right angles to the inner 'members 19.

The apron 22 is made in three sections 23,

24 and 25, the wings 23 and 24,-being made to overlap the center or stationary section 25. The stationary section 25 is fastened along its rear edge to-the support 12 by suitable fastening devices 26. while the wing sections 23 and 24 are securedto one of the forwardly projecting members 21 of the shields 20 and to one ofthe sliding bars 18 in any suitable and well knownmannensuch as by a strip 27 and the fastening devices 28. The adjacent edges of the wing sections.

23 and 24 are cuton an angle as at 29 so sections curling since the central section is never moved and the weight of the paper stock rests upon the edges of the wing sec; tions. Y r Y From the foregoing it will :be evident that an apron constructed in this manner may be readily and quickly adjusted for different width papers without having to remove any of the parts without the possibility of any of said parts becoming loosened or ac- 'cidentally displaced and since the inner edges or the corners 'of the adjustable sections will not curl the life of the apron is greatly prolonged making a large saving in both time and money;

' It being possible to adjust the apron 7 too quickly and to have the inner end of said apron agreater distance from the slice bar when a slow stock is being run to per- Hit the surplus water to flowfrom the paper stock prior to passingbeneath the slice bar.

Qf course I do not wish tobe limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully'd'escribed my invention, what I claim as'new and useful is '1. A paper making machine comprising in'combina'tion, a. slice bar, vertically adjustable brackets for supporting an apron, said apron and means to adjust the apron horizontally relative to said slice bar.

2. In a paper making machine, a slice bar, an apron and meansto adjust said apron vertically and horizontally relative to said slice bar.

3. A paper making machine including an apron, bracketsv to support said apron, means to adjust said apron horizontally on the supporting brackets, and means to adjust the brackets vertically. Y

4. A paper making machine comprising in combination, the machine, brackets seonebeyondea'ch end of the last named slot, and an adjusting screw threaded through each of said lugs, an apron support mount- T ed on said brackets and adjustable horizontally by means of the adjusting screws and fastening means passing through the slots in :the' bracket arms and attached'to the apron support to prevent accidental displacement of the apron support.

tion, the adjacent edges of said wing sections being formed on an angle so that the said edges diverge from the inner toward the outer edges of said wing sections.

7. In a device of the character stated, an apron board, a central stationary apron section supported by said board and projecting from the front edge thereof, and two wing sections connected with said board overlapping and resting upon the ends of the central stationary section.

8. In a device of the character stated, an apron board, a central stationary apron section supported by said board and projecting from. the front edge thereof, and two wing sections connected with said board overlapping and resting upon the'ends of the central stationary section, the adjacent edges of said wing sections diverging from their inner edges toward their outer edges.

9. In adevice of the character stated, an

apron board having a longitudinal arcuate groove thereon, independently sliding bars mounted in saidgroove, shields each com prising two members lying atright angles to one another, one of said members being secured to each of the sliding bars, a central stationary apron section supported by said apron board and projectii-igv forwardly therefrom, and'wing sections overlapping the central section resting thereon and having certain oftheir edges secured to the sliding bars and the other members of the shields. V j

10. In a device of the character stated, an apron board having a longitudinal arcuate groove therein, independently sliding bars mounted in said groove, shields each comprising two members lying at right angles to one another, one of said members being secured to each of the sliding bars, a central stationary apron section supported by said apron board and projecting forwardly therefrom, and wing sections overlapping the central section resting thereon and vhaving certain of their edges secured to the sliding bars and the other members of the shields, the adjacent edges of said wing sections diverging from their inner edges toward their outer edges.

In testimony whereof, I have hereunto aflixed my signature.
